Giant UK telescope gets upgrade (http://news.bbc.co.uk/2/hi/science/nature/3749919.stm)


Work has started to use optical fibres to link up the giant radio telescope at Jodrell Bank with five others that are scattered across England.

The telescopes comprise an array called Merlin that combines the data from each so they perform as a larger telescope.

The telescopes are currently linked by microwaves but replacing them with optical fibres will be a revolution.
...
It is the only instrument observing radio waves that is able to routinely provide images comparable in detail to those obtained by the Hubble Space Telescope.

Interesting(?) quibble - I wonder whether "comparable" is a weasel word, since the VLBA has much higher resolution (albeit with less sensitivity to larger structure).

And a historical note: Lovell himself apparently disliked the Merlin name (MultiElement Radio-Linked INterferometer) so that it was officially MTRLI (T for Telescope) while he was in charge. Only fair to name the 250-foot telescope after him - a real icon of both radio astronomy and space exploration still going strong.
